How can one determine whether to use mysqli or PDO based on the specific requirements of a project in PHP development?

When determining whether to use mysqli or PDO in PHP development, consider factors such as the specific requirements of the project, ease of use, security features, and future scalability. If the project requires flexibility and compatibility with multiple database systems, PDO may be a better choice. On the other hand, if the project needs to interact with MySQL databases specifically and performance is a priority, mysqli might be more suitable. 

// Example code snippet using mysqli
$mysqli = new mysqli("localhost", "username", "password", "database");

if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

// Perform database operations using mysqli

$mysqli->close();
```

```php
// Example code snippet using PDO
$dsn = 'mysql:host=localhost;dbname=database';
$username = 'username';
$password = 'password';

try {
    $pdo = new PDO($dsn, $username, $password);
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch (PDOException $e) {
    die("Connection failed: " . $e->getMessage());
}

// Perform database operations using PDO

$pdo = null;
